Title: Improvements in pressure indicating and limiting devices more particularly for pneumatic tyres
IPC: B60C23/04
Filed: 1933-11-22
Abstract: 424,227. Fluid - actuated valves. ROSENTHAL, H., and CANNATA, A., 10, Via Emanuele Filiberto, Milan, Italy. Nov. 22, 1933, Nos. 32622, 32623, and 32634. Convention dates, Nov. 22, 1932, March 21, 1933, and June 13, 1933. [Class 135] [See also Group XXXIV] A pressure-control device, particularly for use in connection with pneumatic tyres, comprises an excess-pressure relief-valve and an audible signal-device, the relief - valve being silently operated, and the signal actuated only when the pressure falls below a predetermined minimum. As shown in Fig. 1, the device comprises cylindrical casing 1 fitted with a spring-loaded piston 3 and communicating by a flexible pipe 13 with the valve-nipple 15 of the tyre 14. A non- return inflation-valve is fitted at 11 so that normally the piston 3 is balanced between the spring 4 and the inflation-pressure of the tyre. On undue rise of the latter, the piston is forced upwardly and a vent or relief-valve 10 is opened by a rod 7 connected to the piston. On fall of pressure in the tyre, the piston moves downwardly and, by means of a rod 6, opens a valve 8 fitted with a whistle 9. Twin tyres may be connected to the one cylinder so as to maintain balance of pressure in the tyres. The spring 4 may be replaced by a fluidpressure device. In the modification shown in Fig. 3, a flexible diaphragm h is normally balanced between the spring and the (tyre) pressure in the chamber 2<1>. The diaphragm carries a plug x formed with ports 41 leading from the chamber 21 to the opposite side of the diaphragm, such communication being normally closed by means of a valve c. On increase of pressure in the tyre, the valve c is opened by abutment of its stem with an adjustable screwed stud a and air escapes through vents 51. On fall of pressure in the tyre, the spring e reacts to force the lower end of the plug x into abutment with the stem of a valve y whereby air escapes from the chamber 2<1> over a whistle n. In a further modification, a tappet-arm carried by the diaphragm h is arranged to co-operate with a second diaphragm associated with the signalcontrolling valve. The Specification as open to inspection under Sect. 91 describes also a modification of the device shown in Fig. 1, in which the signalcontrolling valve is carried by the piston. This subject-matter does not appear in the Specification as accepted.

Patent GB-904880-A (GB)
Title: Modified clay complexes and method of preparation
IPC: C09C1/42
Filed: 1959-09-29
Abstract: Modified clay complexes are obtained by reacting a clay, in which at least some of the exchangeable ions other than sodium ions have been replaced by sodium ions, with an onium compound, or compounds, defined as A(y - 1) X+B-, where y is an integer having a numerical value equal to the highest positive valence of X, X is selected from N, P, As, Sb, O, S, Se, Sn and I, A(y - 1) represents at least one organic radical, preferably including at least 10 carbons, and as much hydrogen as is necessary to satisfy the formula, and B is an anionic group, such as hydroxide or acetate.  The clay may be bentonitic, and preferably has at least 90% of the exchangeable ions as sodium ions before reaction with the onium compound.  The exchangeable ions may be replaced by means of ion exchange resins, especially high capacity resins such as the sulphonated styrene type cation exchangers, for example Amberlite 1R 120 ("Amberlite" is a Registered Trade Mark) and Nalcite HCR.  A dilute slurry of the clay may be passed through a fixed bed of the resin, which may be regenerated by a concentrated sodium chloride solution. Alternatively the exchangeable ions in the clay may be replaced by repeatedly leaching the clay with a solution of a sodium compound, for example sodium chloride.  The thus modified clay may be reacted with the onium compound either both in the form of dilute dispersions, or in some cases the onium compound may be concentrated. Onium compounds specified include triphenyl phosphonium halides, triphenyl arsonium halides, triphenyl stibonium halides, dialkyl or diaryl sulphonium halides, dialkyl or diaryl selenonium halides, 2:5 dialkyl gamma pyrone hydrochloride, ammonium salts, especially quaternary, for example dimethyldioctadecyl ammonium chloride and dimethyl octadecylbenzyl ammonium chloride, and amines.  The modified clays of the invention may be incorporated with hydrocarbons to form greases.  In an example 60 grams of the modified clay were mixed with 910 grams of a solvent refined neutral paraffin oil, 30 grams of acetone were added, the mixture stirred further, and then pumped through a colloid mill. Specification 664,830 is referred to.
Patent GB-963904-A (GB)
Title: Ferrioxamines and their manufacture
IPC: C12P13/00
Filed: 1960-09-26
Abstract: The Specification comprises brown-red growth promoting substances designated as ferrioxamine A, B, C, D1, D2, E and F.  These substances are organic substances containing nitrogen and iron and are readily soluble in acids and polar solvents such as water, dimethyl-formamide, glycol, ethyleneglycol-mono-methyl ether and lower aliphatic alcohols such as methanol.  Hydrolysis with dilute hydrochloric acid produces inter alia succinic acid, 1-amino-5-hydroxylamino-pentane, cadaverine, and hydroxylamine. Crude ferrioxamine may be produced by a wide variety of fermentation processes including the culturing of algae, Streptomyces, bacilli and yeasts, as well as by extraction from the organs of higher plants such as mono-, and dicotyledoneae.  Preferably fermentation is effected under aerobic conditions in an aqueous nutrient solution containing carbohydrates, nitrogenous compounds and inorganic salts until the solution displays a substantial ferrioxamine action.  The crude material may then be isolated by adsorption on carbon or clays or ion exchangers, by selective extraction with organic solvents by ebetrophoresis, or by chromatography. The individual ferrioxamines may be separated one from another by chromatography. They possess marked anti-anaemic properties. Ferrioxamine A has an elementary analysis of C44.21%, H7.52%, N12.63%, Fe7.95% and C15.93%; it has an equivalent weight of 634; absorption spectrum (H2O) lambdamax=430 mm , E1%1em=37.0; and the IR-spectrum in potassium bromide has bands at 2.92, 3.42, 6.10, 6.32, 6.88, 7.92, 8.10, 8.49, 8.98, 9.55, 10.15, and 10.67. Specifications 923,061 and 949,958 are referred to.ALSO:Anti-anaemic preparations are obtained by mixing the substance ferrioxamine B (which contains nitrogen and iron-see Division C2) with a vehicle such as gelatine, lactose, starch, magnesium stearate, talc, vegetable oils, benzyl alcohol, gums, polyalkylene glycol, while petroleum jelly or cholesterol.  These preparations may be used in solution, suspension or emulsion from or as a powder.
Patent GB-536905-A (GB)
Title: Improvements in or relating to method of and apparatus for drying printing ink
IPC: B41F23/04
Filed: 1939-12-30
Abstract: 536,905. Gas burners. INTERCHEMICAL CORPORATION. Dec. 30, 1939, No. 33098. Convention date, Jan. 6. Addition to 528,270. [Class 75 (i)] [Also in Groups XIII and XVI] In the method and apparatus described in the parent Specification for drying printing ink containing a volatilizable inflammable solvent after the ink has been applied to a material, the cooling air applied to the gas burners is not directed into the combustion zone but away from the burners, to prevent cooling of the flame and the material. Regulated amounts of air may afterwards be directed to the combustion zone to assist combustion of the solvent vapour. The drying apparatus comprises a housing with insulated walls containing two air distributing chambers 36 adjacent to the side walls, and a central exhaust chamber 38. The printed paper or like web 10 is fed through horizontally, and is heated by a number of burners 48 each providing a ribbon of flames transversely across the web. Each burner consists of a gas chamber 52 with a bottom opening covered by a plurality of plates 60 of ceramic refractory material held by angle plates 62. The plates provide a series of orifices 64 opening into a trough-shaped combustion space 66. The width of the flame may be adjusted by slides 68. The burners are so mounted at their ends in the casing walls that they are readily detachable, and removable on removal of the bottom member 26. The insulated side walls 90 which are removable with the burner, form passages 92 which conduct cooling air from the inlet 36 to the clamping members 62, from which it is deflected upwards by a guide 94 secured to the wall 90. Openings 98 allow the air to pass into a channel 100, between adjacent walls 90, and burned solvent vapours are drawn upwards from the combustion zone through passage 102, and thence to exhaust flue 104. This flue is controlled by damper 106 connected to solenoidcontrolled lever 110, so that the damper is closed when the press stops and burners are extinguished. In normal use, some combustion products and unburnt vapour pass through opening 46 into a chamber 116 where combustion is completed and the products are discharged through flue 118. Dampers 122 are provided whereby cooling air may be deflected downwards, as desired, into the combustion space. Closure of the damper 106 when the press stops prevents burning of the web by residual heat in the burners, by ensuring that all the cooling air is deflected downwards to cool the web. In a modification, Fig. 5 (not shown), diversion of the cooling air is effected without the damper 106 by hingeing the guides 94 so that the outlet at their upper end can be closed and a passage at their lower end opened. Specification 522,654, [Group XIII], is referred to.

Title: Polyspirane resin dispersions
IPC: C08G4/00
Filed: 1959-09-30
Abstract: Pentaerythritol, or a mixture thereof with up to 50% by weight of dipentaerythritol, and a dialdehyde are dissolved in water or in an aqueous solution of an inert liquid, and heated with agitation at 80 DEG -100 DEG C. under acidic conditions to form a dispersion, which is stable in the absence of a surface-active agent, of discrete insoluble particles of polyspirane in the aqueous liquid.  The dispersions are thixotropic.  They may be cast to form heat-curable films, e.g. for coating metals or wires, for electrical insulation, or as adhesives or impregnating varnishes.  Conventional additives may be incorporated.  Suitable dialdehydes are succinaldehyde, glutaraldehyde, suberic aldehyde, azelaic dialdehyde, sebacic dialdehyde, phthalic aldehydes or mixtures thereof.  Suitable inert liquids which may be used are dioxane, dimethyl suphoxide, alcohols and dimethyl formamide.  The acidic conditions for polymerization may be produced using inorganic acids, e.g. hydrochloric, sulphuric or phosphoric; organic acids, e.g. oxalic, p-toluenesulphonic, or formic, or acid compounds, e.g. anhydrides, AlCl3, SnCl4, or TiCl4. A pH of 2-3,5 is preferred.  In examples (1).  Technical pentaerythritol containing 12% by wt. of the dimer was mixed with a 25% aqueous solution of glutaraldehyde and with water and oxalic acid is added to a pH of 2,65.  The mixture is heated with stirring at 90 DEG -100 DEG C. for 8-12 hours.  (2) Terephthalaldehyde is used with sulphuric acid, and some methanol is included in the reaction medium. (3) Uses succinaldehyde with pentaerythritol and formic acid. Examples 4-9 describe the preparation of a series of dispersions from glutaraldehyde and technical pentaerythritol using different rates of agitation and substantially constant degrees of acidity.  The effect on the particle size of the dispersions was then observed.  In Example 10 a polyspirane dispersion with 23% by weight solids was diluted with water was coated on to a copper wire and heat cured after each coat.  Six coats were applied in all to give a well insulated wire.
